“My Kids Are Becoming Plastic”: Why Cillian Murphy Left London and a Massive Movie Deal to Save His Sons from a Posh Upbringing in Ireland

By Celebrity Lifestyle Desk | December 28, 2025

Cillian Murphy is often described as “the most reluctant superstar in Hollywood.” While his peers are frequently spotted at swanky Los Angeles galas or elite London social clubs, the Oppenheimer star has spent the last decade doing everything in his power to keep his distance from the “plastic” side of fame.

The most dramatic evidence of this came when Murphy decided to leave London—a city where he had lived for 14 years and where his career was booming—to return to his native Ireland. The reason? He noticed his sons, Malachy and Aran, were developing “posh” English accents and a worldview he felt was detached from reality. In his own words, he feared his children were “becoming plastic.”

The “Posh” Realization

For over a decade, London was home for Cillian and his wife, artist Yvonne McGuinness. It was the hub of his professional life, the place where he filmed Peaky Blinders and The Dark Knight Trilogy. But as his sons grew older, Cillian began to notice a shift in their identity that deeply unsettled him.

“They were sounding very posh,” Murphy later admitted in a candid interview. “They were developing these very fine English accents, and I don’t think that was something I was comfortable with. We wanted them to be Irish.”

For Cillian, the accent was just the surface. He worried that the elite environment of London’s high-society circles was shielding them from the “real world.” He wanted them to have the same grounded, slightly gritty upbringing he had in Cork—one where you aren’t judged by your father’s Oscar, but by your own character.

Walking Away from the Deal

Reports from the time suggest that Cillian’s decision to move wasn’t just a lifestyle change; it involved a significant professional sacrifice. Sources claim that Murphy walked away from a massive, long-term “first-look” movie deal with a major London-based studio because it would have required him to remain in the city for several more years.

“He put his family before his bank account,” an industry insider shared. “Most actors would have taken the money and put the kids in a private boarding school. Cillian chose the move. He wanted to be a present father in a place that felt like home.”

The Return to Ireland

In 2015, the Murphy family settled in a quiet, coastal area of South Dublin. Since then, the transformation has been exactly what Cillian hoped for. His sons are now teenagers with Irish accents and a lifestyle that revolves around the outdoors and music rather than red carpets.

Cillian has famously stated that he enjoys the “anonymity” of life in Ireland. While he is a national hero, the Irish people generally respect his privacy, allowing him to shop for groceries or walk his dog without the paparazzi frenzy that follows him in London or NYC.

• The Grounding: By living in Ireland, Cillian’s sons are exposed to a culture that values modesty and humor over celebrity status.

• The Shield: Moving away from London’s media hub acted as a natural barrier between his children and the “noise” of the entertainment industry.

• The Results: His son, Aran Murphy, has since begun his own acting career, recently landing a role in a major film, but with a work ethic and humility that many attribute to his upbringing in Dublin.

The “Brutal Truth” About Fame

Cillian Murphy’s “built different” mentality is rooted in a brutal truth he discovered early in his career: Fame doesn’t make you a better person; it just makes life more complicated.

“I’m just a guy who gets paid to make faces,” Cillian has often said. By moving his family to Ireland, he ensured that his sons saw him as a father first and a “star” second. He rejected the “posh” upbringing because he knew it was a gilded cage. He wanted his sons to be free to be themselves, not “the sons of Cillian Murphy.”

The Verdict

Today, Cillian Murphy stands as a rare example of a Hollywood titan who successfully navigated the minefield of celebrity parenting. By choosing “plastic-free” Ireland over posh London, he saved his sons from the very thing that consumes so many celebrity children: a loss of identity.

He may have left a massive movie deal on the table, but as his sons grow into grounded young men, it’s clear that Cillian Murphy made the best deal of his life.
